| Nuclear hypertrophy [n (%)] | 0 (0) | 14 (88) ** | 19 (82) ** | 7 (100) ** |
An abnormal electrocardiogram is characterized by the presence of rhythm disturbances, conduction defects, signs of left ventricular hypertrophy, or abnormal repolarization.
* P < 0.05 compared to the other groups.
** P < 0 .01 compared with control donors.
